数字多用表自动检定系统设计

数字多用表型号多、功能多、检定项目多,每项具有多个量程,且各量程准确度不一,同一量程在不同检定点其技术指标也不尽相同,采用传统手动检定耗时耗力、误差大、错误几率高、工作效率低.在VEE Pro软件开发平台上,设计开发出一套数字多用表自动检定系统.该系统包括仪器信息记录、带接口数字多用表检定、不带接口数字多用表检定及打印输出四个模块,测试过程采用实时测试显示,自动进行数据处理并存档.使用结果表明:该系统操作简便,提高了工作效率及准确度,减小了人为误差,确保了测试数据准确可靠.

Design of the Digital Multimeter Automatic Verification System

The digital multimeters have been a lot of models and any model has been multi-function and variable verification items.Moreover,each item has several ranges which are variable in accuracy,even in the same range,the specifications vary from different verification points.The traditional manual verification of digital multimeter contains some problems like notable errors,high error rate and low efficiency.Based on the VEE Pro software exploitation platform,a system of digital multimeter automatic verification...
